We present a case of pseudoelectrical alternans occurring during supraventricular tachycardia.

This paper reviews the anatomical substrates responsible for the induction and maintenance of supraventricular tachycardia and discusses the ECG findings associated with these tachycardias. The normal anatomy of the supraventricular conducting system, particularly within the atria, is complex with conduction proceeding along preferential pathway, which are in turn determined in part by the anis...

Abstract Management of fetal supraventricular tachycardia at times can be tricky and challenging when they are secondary to underlying metabolic or hormonal problems. It difficult unmask the real culprit unless thorough evaluation is performed.

DURING THE ACUTE phase of myocardial infarction in man, supraventricular tachyarrhythmias may be observed in 10% of all patients." 2 Their onset is often heralded by frequent supraventricular extrasystoles, which may escape detection by conventional monitoring techniques. The mechanism of their genesis is still debated: atrial stretch caused by incipient ventricular failure, ischemia of the sin...

The authors would like to thank Professor Halil Dogan (Bakirkoy Dr. Sadi Konuk Training and Research Hospital, Istanbul, Turkey) for informing them of the following error. The following sentence within the last paragraph of the ‘Diltiazem and Atrial Arrhythmias’ section, ‘‘A retrospective study evaluated 77 patients with supraventricular tachycardia treated with oral adenosine or intravenous di...

UNLABELLED A young man underwent 2 catheter ablation procedures because of frequent episodes of paroxysmal supraventricular tachycardia (SVT). A left accessory pathway was ablated in the first procedure. The patient underwent the second ablation procedure due to a recurrent SVT demonstrated by 12-lead electrocardiogram two weeks after the first procedure. During the second procedure, a SVT with...

Background: Arrhythmias in neonates are not common and usually affect newborns with a normal heart or those that suffer from structural heart disease. A malignant type of arrhythmias is supraventricular tachycardia. Meanwhile, one uncommon type of supraventricular arrhythmias is atrial flutter (AFL), which is founded upon reentry mechanisms in the atrium. The AFL may result in heart failure or ...
